Specification of Letters Patent.

Patented July 20, 1909.

Application filed April 13, 1907. Serial No. 367,939.

T 0 all whom it may concern:

Be it known that I, ROBERT J. NionoLsoN, citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Bookbinders, of whichthe following is a full, clear, concise, and exact description,reference being had to the ac comp anying drawings, forming a p art ofthis specification.

My invention relates to book binders and will be hereinafter disclosedby reference to the accompanying drawing, showing the preferredembodiments of the invention, and the invention will be p articularlypointed out in the claims.

In the drawing-Figure l is a perspective view of one embodiment of theinvention. Fig. 2 is a sectional view on line 2 2 of Fig. 1. Fig. 3 isan end view showing a book held in place by a metal strip, analternative position of the metal strip being shown in dotted lines.Fig. 4c is a perspective view showing in full lines the position of themetal plate indicated by the dotted lines in Fig. 3. Figs. 5 and 6 areperspective views of a modification of the structure shown in Figs. 1 to4, inclusive, Fig. 5 showing the holding position of the device whileFig. 6 shows the holding device in an alternative position. Fig. 7 is asectional elevation of the parts as indicated in 5, the position of theholding device as indicated in Fig. 6 being shown in dotted lines inFig. 7. Figs. 8 and 9 show another construction, the holding devicebeing shown in alternative positions in these two figures. Fig. 10 is aview of the holding device entering into the construction of Figs. 8 and9.

Like parts are indicated by similar characters of reference throughoutthe different figures.

The back element a constitutes a separable cover designed to engage thebacks of books, such as magazines, a book I) being shown provided withsuch a cover. In order that this back element may engage the back of abook, it is preferably provided with upwardly extending arms 0 securedto the back element in any suitable way. In the preferred embodiment ofmy invention, these upwardly 1 extending arms 0 constitute the angu arends of a metal strip 01 which is caused to form a part of the backelement a. One of the l arms 0 desirably carries a prong or prongs cwhile the other arm 0 is provided with an opening through which thereduced end of a bar 6 is inserted, this bar a being so shaped that itmay be projected outwardly to a limited extent. The bar 6, for thepurpose last expressed, is desirably wedge-shaped, the larger end of thewedge being containable between the held in place. The bar 6 ispreferably fiat and occupies a position that is perpendicular to theplane containing the long and intermediate portion of the metal strip(1, when said bar is taking part in holding a book within its cover. Inother words, this bar, when performin this function, occupies a planesubstantia ly perpendicular to the back of the book proper. In orderthat the bar 6 need not be removed bodily from the structure each time abook is to be inserted or replaced, I provide structural featureswhereby that normal inter-relation and relative position of thebar 6 andthe associate arm 0 may be changed without effecting the removal of saidbar, yet which change in relation and position will permit the book tobe inserted or replaced. In the normal position of the bar within theaperture 0 of the associate arm 0, that position in which said bar holdsthe inserted book in place, the said bar is incapable of materialmovement,because the book confines it in such slight movement as it ispermitted to have, to the plane it then occupies. Aperture 0" iselongated vertically and contracted horizontally to hold strip 6vertical when in holding position.

Respecting the construction shown in Figs. 1 to 4, when it is desired toinsert or replace a book, the bar 6 need only be drawn in until the linkf projects sufficiently within the book space to permit the elevation ofthe bar, which elevation may then be suiiicient to permit the insertionand replacement of books. In order to restore the book holding positionof the bar 6, said bar need only be placed in a plane perpendicular tothe back of the book and thereafter projected outwardly through theassociate arm 0, so

that said arm cooperating with the contained book will maintain the saidbar in a plane substantiallyperpendicular to the back of the book, whereby said book is held in place. In order to maintain the bar 6 inpermanent relation with the associate arm 0, the linkf has a suitableimpediment upon the exterior of the arm 0 to prevent the stateddisplacement of leaves of the book that is to be the bar, thisimpediment desirably residing in a spiral ring g, though I do not wishto be limited to this arrangement.

In the construction shown in Figs. 5, 6 and 7, the bar 6 is also limitedin its movement when holding a book in position.

In order to be able to swing the bar 0 clear of the book, when said bookis to be inserted or replaced, I bend said bar at h, in the constructionshown in Figs. 5, 6 and 7, this bend permitting the bar 6 to swing in aplane substantially perpendicular to the back of the book, when said baris rotated a quarter turn from the position it occupies when helding thebook in place. In order to facilitate the turning of the bar a quarterturn, in or der that it may thereafter be swung clear of J the book topermit the insertion or replace-- serves as an operating handle for thepurpose expressed.

In Figs. 8, 9 and 10 is shown another embodiment of the invention inwhich the narrower end of the plate a is turned over in substantiallythe plane of the plate, so that it may occupy a holding position asindicated in Fig. 8, in which position it is farthest projected towardthe fastening prong c, and so that it may be moved into the positionshown in Fig. 9, whereupon the book may be withdrawn. In order to permitof the adjustment shown in Fig. 9, the fastening plate 0 is movedlongitudinally away from the prong c" and thereafter swung backward.

The position to which the bar may be swung, in order to clear the spaceoccupied by the book, is shown in dotted lines.

Iclaim as new and desire to secure by Letters-Patent the following:

1. A device of the class described including a cover structure withinwhich a book may be separably contained, a bar engaging an element ofsaid structure and bent near where it engages said element of the coverand thereby being permitted. to swing away from the book when said baris shifted from its book-holding position by reason of the bend in thebar, said element of the cover structure having this engagement with thebar being in the form of an arm provided with an opening which receivesthe bar and permits the same to project outwardly to a limited extent.

2. A device of the class described including a cover structure withinwhich a book i may be separably contained, a bar engaging an element ofsaid structure and bent near where it engages said element of the coverand thereby being permitted to swing away from the book when said bar isshifted from 7 its book-holding position by reason of the bend in thebar.

8. A device of the class described including a co er structure withinwhich a book may be separately contained, said cover structure includingan apertured arm, a bar adapted to project through said opening to alimited extent and having inter-connection with the arm w 1ich permitsthe bar to swing clear of the book held by the cover, whereby the covermay have a book engaged there with or removed therefrom withoutseparating the connection of the bar and arm.

4. A device of the class described including a cover structure withinwhich a book may be separaljily contained, a bar engaging an element ofthe cover structure, said element of the cover structure having anaperture through which said bar projects, said aperture being elongatedvertically and contracted horizontally to hold the bar in a verticalplane when said bar is in a book-holding position.

In witness whereof, I hereunto subscribe my name this 13th day ofFelu'uary A. D., 1907.
